Regard B2B electron business affairs as the website, the page of correspondence of place of the one class that the product classifies, 2 class is channel page and column page respectively, it is extremely tall that page content is spent related the keyword of set to it, if match the URL with the standard, the weight of the page is met perfectly, so its secure general channel page, column page rank of keyword, core keyword is before leaning quite, what should make great efforts truly is final page and home page.

作为B2B电子商务网站，产品分类的一级、二级所对应的页面分别是频道页和栏目页，页面内容与之设定的关键词相关度是极高的，如配与规范的URL，页面的权重会相当不错，所以一般的频道页、栏目页其固定关键词、核心关键词排名都是比较靠前，真正要下功夫的是最终页和首页。
